Abstract: A master device communicates with a slave device through an asynchronous serial communications link. The master device includes a single pad configured to communicate a command frame including an address and a data frame including data with the slave device via a single wire; and a processing circuit configured to generate an oversampling clock signal from a clock signal, to perform a synchronization process for selecting one of a plurality of clock phases of the oversampling clock signal, and to perform a sampling process for sampling an each bit value included in the data frame transmitted from the slave device using a clock phase at the same position as the clock phase selected during the synchronization process.

Abstract: A method and apparatus for tracking input positions via Electric Field Communication (EFC) are provided. The apparatus includes a plurality of receiving electrodes for EFC and a receiver unit. The receiving electrodes detect strengths of input electric fields. The receiver unit compares the strengths of the input electric fields with each other and generates position information regarding the input electric fields.
